Carefully lift and pull the platform from the dispenser and place it in a clean and well lit area 
for service.

1.

Remove platform as described above in removal of platform instructions.

2.

Remove the two white plastic hose clamps from the pump tube connections. Remove the two 
stainless steel concentrate delivery tubes from the hose ends.

3.

Loosen and remove the four thumb screws from the pump body.

4.

Remove the rear half (only) of the pump body to reveal the hose and rollers.

5.

Remove the old hose from the pump body. If the rollers come out with the hose, place in back 
into the housing being sure to align the roller assembly shaft keyway to the motor shaft key 
so that the two interlock (see figure 3 for step by step pictorial instructions).

6.

Firmly press the new hose into the pump body around the roller assembly, being sure to keep 
the protruding ends even with each other. Once the hose is in place, replace the outer half of 
the pump body. Hold the tubing in place inside pump housing with one hand, capture the lower 
part of the tubing with the outer housing, then proceed to capture the shaft of the roller assem-
bly and push the housing straight onto the pump/motor portion of the assembly. Make sure to 
capture the hose within the body and not pinch it between the halves. Do not use any tool 
other than your finger tips to manipulate the hose into the housing or damage to the hose will 
result.

7.

While holding the pump halves together by hand, reinsert the four thumb screws and tighten 
them in a criss-cross pattern until the two halves are pressed together.

8.

Insert the two stainless tubes into the hose ends and fasten them with new clamps using pliers 
to tighten the clamps.
